As far as I know I have no chip however I belive my O2 sensor has been eliminated. I have a mild cam and intake with the bigger throttle body and acording to the people on fullsizebronco.com my truck shouldn't run. I did however "think" I had 24# injectors on my motor (a "good" mechanic had told me that before I knew better) and a kid at autozone swore they were stock 19# so I ran the numbers on the injectors and low and behold, they're stock. I'll tell you though, the mods I have are some pretty cool mods and when timed right (didn't tighten the dizzy down after great timeing thanks to an older fellow) it'll burn 33x12.50's just by mashing the loud pedal. It doesn't do it like a drag car but it'll sure get it if you don't back pedal a bit. I put my truck against my buddies 00 Grand Prix GTP (supercharged) and from the line I had him untill around 40 but then he just ran all over me. Not to bad for a 2 and a half ton 4x4 though. I understand my truck isn't a race car too but I love the loud pedal and I think I was born with lead bones in my right foot. It'll get-r-done trying to get on the interstate too, no problem there. It'll actually out eccelerat my wifes 96 crown vic old sherrifs car. Not to shabby...
